Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SI | input | Serial Input (MOSI). Shifts command, address, and write data into the device; latched on the rising edge of SCK. Ignored while CS is deasserted (high). |+| 2 | SCK | input | Serial Clock. Provides the clock reference for the SPI interface; SI is sampled on the rising edge and SO is driven on the falling edge. Supports up to 85 MHz in RapidS mode. |+| 3 | RESET | input | Active-low hardware reset. A low level terminates any operation in progress and holds the internal state machine in idle; normal operation resumes when driven high. Internal power-on reset covers power-up; tie high externally if unused. |+| 4 | CS | input | Active-low chip select. A high-to-low transition starts an SPI operation; a low-to-high transition ends it. When high, the device is deselected, SO goes high-Z, and SI is ignored (device normally enters standby). |+| 5 | WP | input | Active-low write protect. When asserted, all sectors marked in the Sector Protection Register are protected against program/erase regardless of software protection state; the Sector Protection Register itself becomes non-modifiable. Internally pulled high; may be left floating but tying to VCC is recommended. |+| 6 | VCC | power_in | Device power supply. 2.5 V to 3.6 V for the -SHD- (D) voltage option. Operation outside the valid VCC range may produce spurious results. |+| 7 | GND | power_in | Ground reference for the power supply. Connect to system ground. |+| 8 | SO | output | Serial Output (MISO). Shifts data out of the device on the falling edge of SCK. High-impedance while CS is deasserted (high). Clock-to-output time tV of 6 ns maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Dialog Semiconductor Adesto Adesto Technologies |+| Package | SOIC-8-208mil |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT45DB161E-SHD-TSHD-B`+- `AT45DB161E-SHD-TSHD-T`+- `AT45DB161E-SHD-TSHF-B`+- `AT45DB161E-SHD-TSHF-T`+- `AT45DB161E-SHD-TSHD2B-T`+- `AT45DB161E-SHD-TSHF2B-T`+- `AT45DB161E-SHD-TSHFHA-T`+- `AT45DB161E-SHD-TSHFHC-T`+- `AT45DB161E-SHD-TSSHD-B`+- `AT45DB161E-SHD-TSSHD-T`+- `AT45DB161E-SHD-TSSHF-B`+- `AT45DB161E-SHD-TSSHF-T`+- `AT45DB161E-SHD-TSSHD2B-T`+- `AT45DB161E-SHD-TSSHF2B-T`+- `AT45DB161E-SHD-TSSHFHA-T`+- `AT45DB161E-SHD-TSSHFHC-T`+- `AT45DB161E-SHD-TMHD-Y`+- `AT45DB161E-SHD-TMHD-T`+- `AT45DB161E-SHD-TMHF-Y`+- `AT45DB161E-SHD-TMHF-T`+- `AT45DB161E-SHD-TMHD2B-T`+- `AT45DB161E-SHD-TMHF2B-T`+- `AT45DB161E-SHD-TCCUD-T`++## CAD (KiCad official)++- Symbol: `AT45DB161E-SHD-T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8-208mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Dialog Semiconductor Adesto Adesto Technologies datasheet](docs/at45db161e-shd-t-datasheet.pdf) (73 pp, sha256 `6ce69d9e374fdde0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
